Engine mounts are perfectly fine, hardly any movement.

If I coast gently and come to a gentle stop everything is normal. It's if I go really hard on the brakes and stop as hard as I can withoput ABS kicking in then it will feel like a rear ending.

Guibo was fine aswell along with the tranny mounts aswell

The fluid has now gone through 2 changes.

Spoke to another 2 tranny people and they both now reckon it's probably something internal and needs taking apart.
